    Are you looking at 3D Finished ? or 3D Unfinished?

    I figured it out as soon as you asked the question. I was using side view & never noticed the other choices in the pull down box. All is well. :rolleyes:

    I'm designing a rocket that has a nosecone that is larger in diameter than the body tube, so I need standoffs for the launch lugs. I created 2 short trapazoidal fins and positioned them where the launch lugs are, but I can't figure out how to move them up off the body tube to the top of the standoff. What's the trick? o_O

    K'Tesh, I'm trying to create a ork file of the Kraken. Making tube fins is easy but how does one alter the shape of a tube fin? Can it be done?

    Can't be done in any practical way, sorry.

    I should probably clarify. If your goal is to come with something that really *looks* like the Kraken, you're out of luck. If you just want to simulate its flight characteristics and don't care so much what it looks like, then you can probably get a reasonable approximation but just putting in standard tube fins with length equal to the "average" length of the Kraken tubes.

    Neil is correct. the only thing I could think of would be to "fake" the sloped cuts with a "decal", I was also thinking that if OR could be made to allow for transparent sections to accept decals with transparent sections it could also be faked, but for now... It's not possible.

    Yes, I'm wanting to see the flight sims of the Kraken & not so much the exact look. What's you best guess on the average length? They are 7" long at the body tube and 1.5" at the top. I'm guessing around 2.5" - 3".

    That sounds reasonable.

    If you happen to do this sim, try also putting on four sets of three fins, each the shape of the kraken fin seen from the side. I'd be curious how well either method squares with real life.

    Perhaps it's now a good time to spin the Kraken tangent off into its own thread?

    OK. You really think so? I'm a newbie but with enough effort I figure things out. Plus I am a computer nerd. Worked as an IT guy for 25 years. A hobby that went awry. :rolleyes:

    Try Paint.net. It's free & much better than MS Paint.

    I did a build thread of my Kraken some time ago. Snkrl posted a helpful tip that will work for you (Here).
